JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives

The subject provide process of estimations required for various work in

construction. To have knowledge of using SOR & SSR for analysis of rates on various works and basics of planning tools for a construction projects.

Course Outcomes

On completion of the course, the students will be able to:

• understand the technical specifications for various works to be performed for a project and how they impact the cost of a structure.
• quantify the worth of a structure by evaluating quantities of constituents, derive their cost rates and build up the overall cost of the structure.
• understand how competitive bidding works and how to submit a competitive bid proposal.
• An idea of how to optimize construction projects based on costs
• An idea how construction projects are administered with respect to contract structures and issues.
• An ability to put forward ideas and understandings to others with effective communication processes
